Title: Method and apparatus for drying organic material
Inventor: MOORE PHILIP COLEY
IPC: F26B11/04
Filed: 1996-03-25
Abstract: An apparatus and method of separating organic mass into its component parts in environmentally contained hygienic conditions at high thermal efficiency. One example is extraction of aromatic oils from citrus fruit. Organic materials derive from plants which contain (A) dry matter; (B) aqueous solutions and (C) secretions. The apparatus and method separates organic mass into these three components to create positive valuable products, frequently from negative value wastes. The apparatus and method utilise a drying medium comprising a mixture of self-derived superheated steam generated from part of the moisture given off by the material itself and air. The apparatus is fully enclosed, thus being environmentally benign and eliminating odours and deleterious emissions common to non-contained and/or direct fired dryers. Enclosure and use of superheated steam for drying, plus the combination of several processes in one operation, leads to higher thermal efficiency and lower operating costs than conventional drying or distillation processes.

Filed: 1996-06-06
Abstract: An apparatus (100) and method are disclosed for measuring the desired length of a prosthetic device (104) which is to be implanted in a body cavity (202) of a patient. The apparatus (100) generally includes a helically coiled stent (104) formed of a resiliently-deformable material, a plunger (102) which is connected to the proximal end (118) of the stent (104), a sheath (106) which slides over the plunger (102) and stent (104) when the plunger (102) and sheath (106) are used to insert and removably deploy the stent (104) into the body cavity (202), and a scale (122) for measuring an indication of the length of the stent (104) once removably deployed in the body cavity (202). Proximal movement of the sheath (106) to partially deploy the stent (104) causes a length to be indicated on the scale (122). According to the method of the invention, the helically coiled stent (104) of the apparatus is placed and partially deployed within the body cavity (202) by use of the plunger (102) and sheath (106) of the apparatus (100). Once the stent (104) bridges the body cavity (202), the scale (122) of the apparatus (100) is used to determine the length of the deployed stent (104). The apparatus (100) is then removed from the body cavity (202), and a stent similar to the stent (104) of the appartus is cut to the length indicated on the scale (122). In a second embodiment of the apparatus (300) and method, the stent (304) of the measuring apparatus (300) is substantially non-porous to allow occlusion of side vessels (302, 303) extending from the body cavity (301). The patient is then monitored for any ill effects resulting from the occlusion.

IPC: H04L12/56
Filed: 1996-06-26
Abstract: A telecommunications apparatus for transporting ATM cells having either of isochronous units of payload data and asynchronous units of payload data, between receiving and transmitting ports includes a buffer for asynchronously queuing units of payload data received from the receiving ports and for subsequently transmitting the queued units of payload data in a time division multiplex data stream toward the transmitting ports. A timeslot interchanger is used to reorder a time defined sequence of isochronous units of payload data from the first data stream into a second time defined sequence of isochronous units of payload data in a second TDM data stream. An outgoing TDM  data stream is assembled by transferring the first data stream into the outgoing data stream while substituting each payload occurrence of isochronous units from the second TDM data stream into corresponding TDM locations in the outgoing data stream. The outgoing data stream is transmitted toward the transmitting ports whereby telephone calls are connected via the isochronous units of payload data. Delay typically inherent in telephone conversations connected via prior ATM facilities and the consequent severe echo often experienced by users is substantially reduced.

Patent CA-2226391-A1 (CA)
IPC: C07K14/715
Filed: 1998-03-13
Abstract: Peptides correspond ing to the N-terminal 9 residues of stromal cell derived factor-1 (SDF-1) have SDF-1 activity. Peptides, corresponding to residues 1-8, 1-9, and a disulfide linked dimer of 1-9, involving Cys-9, induced chemotaxis in T lymphocytes and CEM cells, and bound the SDF-1 receptor, CXC chemokine receptor 4 (CXCR4). The peptides had similar activities to SDF-1, but were less potent. Whereas native SDF-I had half maximal chemoattractant activity at 5 nM, the 19 direr and a 1-9 monomer analog were 100- and 3600-fold less potent, respectively. Receptor desensitization and competition binding experiments indicated that the SDF-1 peptides are specific for CXCR4. As Cys-9 is involved in a disulfide bridge with Cys 34 in native SDF-1, it is possible that the disulfide of the peptide dimer enhances its structural similarity to the native protein. Overall this study shows that the N-terminal region is sufficient to bind and activate CXCR4, which suggests the feasibility of designing small CXCR4 agonists or antagonists.

Title: A method for frequency allocation and assignment in wireless communication systems
Inventor: DONER JOHN R
IPC: H04W16/12
Filed: 1996-10-15
Abstract: A single-cell wireless communication system is partitioned into n sectors, to which channels are allocated from two groups of non-adjacent channels. If the available channels are consecutively numbered from lowest to highest frequency, or vice versa, the groups are, respectively, the even-numbered channels and the odd-numbered channels. These two groups are each subdivided into n/2 sets, with the first set of each group including the lowest numbered channels of the group, the next set including the next lowest-numbered channels of the group, and so forth. The sets are then allocated to the sectors such that the first set of one of the groups is allocated to a first sector, the next set of the same group is allocated to a contiguous sector and so forth, with the last set of the second group allocated to the nth sector.  The dividing points between the sets are selected such that any sector has at most a single channel that may experience adjacent-channel interference from a channel that is allocated from a contiguous sector. Preferably, a channel is selected for assignment to the mobile units such that the selected channel is within a greatest gap between the channels of the same set that are then in use. If the selected channel is the one channel that may experience adjacent-channel interference, another channel may be selected from the set.

Filed: 1996-11-12
Abstract: La présente invention concerne le traitement, en vue de la récupération de ses constituants, d'un matériau se présentant sous forme de fines particules, tel que la poussière de carneau d'un four pour la fabrication de l'acier. Ce matériau se trouvant dans un collecteur (11) est transformé en granules. Une fois séchés dans un séchoir (16), les granules sont introduits dans un premier four rotatif (21) où ils sont frittés, donnant ainsi des granules très durs. Pendant ce processus, les constituants volatils qui se dégagent sont récupérés. Après tamisage pour en éliminer les fines particules de matériau, les granules frittés sont introduits dans un second four rotatif (31) avec un réducteur tel que de l'anthracite finement broyé (35) et lavé. La réduction des granules provoque le dégagement d'un second constituant qui vient alors s'oxyder dans le four rotatif et dont la récupération donne de fines particules d'oxydes. Les granules originaux, qui conservent leur intégrité, forment essentiellement du fer spongieux.
